| English | A | 4.0 | 3 | 12.0 |
| Math | B+ | 3.3 | 4 | 13.2 |

Semester GPA vs Cumulative GPA — What Is the Difference
Semester GPA is calculated using only the courses from one semester. It shows how you performed in that specific term and resets every semester.
Cumulative GPA is the overall average across all semesters completed. This is the GPA that appears on your transcript, matters for graduation requirements, academic standing, scholarships, and graduate school applications.
A strong semester GPA can raise your cumulative GPA over time. One bad semester does not define your overall academic record if you perform well in subsequent semesters.
What Is a Good College GPA
A GPA of 2.0 is typically the minimum required to remain in good academic standing at most US colleges. A GPA of 3.0 is generally considered good. A GPA of 3.5 or above is considered strong and is competitive for graduate school, scholarships, and competitive employers. Many employers and graduate programs look for a minimum of 3.0.

Frequently Asked Questions
How do credit hours affect GPA?
Credit hours act as a weight in the GPA calculation. A 4 credit course counts more than a 2 credit course. If you earn an A in a 4 credit course and a C in a 2 credit course, the A has more impact on your GPA because it carries more weight.
Does a failed course affect college GPA?
Yes. An F earns 0 grade points and the credit hours are still counted in the denominator of the GPA calculation, which lowers your overall GPA significantly. Some colleges allow you to retake the course and replace the F — check your institution’s academic policies.
What GPA do I need for graduate school?
Most graduate programs require a minimum cumulative GPA of 3.0. Competitive programs at top universities often expect 3.5 or above. Some programs also look at your GPA in your major courses separately from your overall GPA.
What is the difference between GPA and CGPA?
GPA usually refers to your grade point average for a single semester. CGPA stands for Cumulative Grade Point Average and covers all semesters combined. Both use the same 4.0 scale at most US colleges.
